Transconductor circuit with high-linearity double input and active filter thereof

The invention relates to a transconductor circuit with a double input and a single output, comprising two input transistors (M1, M2) whose primary conduction terminals (D1, S1, D2, S2) are respectively connected together; in this way, variations in load current and voltage can be made lower, thereby also lowering distortion from changes in their transconductance.
